Payment method in invoice

Hi Guys,

For our invoice documents, the FI documents, the payment method field is blank. We want it to be populated by a specific payment method.

This FI invoice is getting posted from the MIRO transaction .

Do we have to give the payment method at the time of MIRO for the same payment method to reflect in the FI invoice document.

Where can we give the payment method for the Purchase order, so that the corresponding FI document will have the payment method in the document that is getting posted into FI. We want this invoice to be picked , when we specify the same payment method in F110 .

Right now, it wont pick up this invoice, as the payment method field is empty.

Thanks,

Srikanth.
